These pillows are very large and heavy, but you can do a lot with them. I only needed a regular pillow , so I took out enough to make me one and put it in a regular zip pillow protector, you can use these at what ever comfort level you need, I even have enough left for another pillow. If you are reading or whatever  you can fluff up or down.  This are the best pillow I have slept on. The outside cover is nice, I will take some off the length and use it. It is not hot at all.  Very good sleeping, thank you.
